摘要：

Malignant tumors account for most sources of ectopic ACTH Cushing syndrome (EA-CS). Early localization of the source and complete removal can be curative and also prevent metastasis. Diagnostic CT is known to perform better than PET/CT (low dose) in characterizing lung pathologies. However, bronchial carcinoids, a common source of EA-CS, may be difficult to detect on chest CT scan especially when it is small and located close to the hilar region. We present a case of EA-CS due to bronchial carcinoid, which was easily seen on Ga-68 DOTANOC PET/CT after a diagnostic chest CTwas reported as normal.
